Event rental Sales Needed After a Discount
Required sales = ceiling(original contribution / discounted unit contribution)
Gather rental contracts, asset records and maintenance logs. Include transport, setup, and cleaning. The starting figures are examples. Replace them with your own records.
Formula and worked example
Required sales = ceiling(original contribution / discounted unit contribution)
| Input | Example |
|---|---|
| Original selling price | 100 |
| Variable cost per sale | 60 |
| Price discount | 10 % |
| Original sales volume | 100 |
| Calculated result | 134 sales |
Choose reliable inputs
Account for turnaround, maintenance and available inventory before accepting another booking. For this event rental calculation, use rental contracts, asset records and maintenance logs and a consistent definition of one rental booking.
- Transport: include the portion belonging to this rental booking or reporting period, and record where the value came from.
- Setup: include the portion belonging to this rental booking or reporting period, and record where the value came from.
- Cleaning: include the portion belonging to this rental booking or reporting period, and record where the value came from.
Use the same currency for every money input. Do not mix weekly costs with monthly revenue, or count the same expense in both an itemised cost and allocated overhead.
Will a 10% discount need only 10% more sales?
Use contribution after variable cost. The discounted price must still exceed variable cost.
What if this input changes?
If original selling price rises by 10%, this example changes by -5 sales. This shows the effect of one change; it does not predict what will happen.
Open the calculator, save your baseline, then change the input supported by the least reliable estimate in your records. Compare both scenarios before committing to a price or capacity promise.
